Job description

Back End Engineer - New Ventures

Hybrid in London, United Kingdom (At least one day in office per week)

Overview

We’re looking for a back-end engineer to join the Credit Compass team.

You will help design and build the scalable, high-performing services that power Credit Compass, helping small businesses understand, monitor and improve their credit health.

The company

Small businesses move fast. Opportunities often don’t wait, and cash flow pressures can appear overnight. To keep going, and growing, SMEs need finance that’s as flexible and responsive as they are.

That\'s why we built iwoca. Our smart technology, data science and five-star customer service ensures business owners can act with the speed, confidence and control they need, exactly when it\'s needed.

We’ve already cleared the way for 100,000 businesses with more than £4 billion in funding. Our passionate team is driven to help even more SMEs succeed, through access to better finance and other services that make running a business easier. Our ultimate mission is to support one million SMEs in their defining moments, creating lasting impact for the communities and economies they drive.

The team

The Credit Compass team is responsible for helping small businesses understand, monitor, and improve their credit health by turning complex financial data into clear, actionable insights. The team owns the product end-to-end, from integrating data sources and shaping scoring logic through to designing the dashboards, journeys, and nudges that keep customers coming back. It is a cross-functional team of front-end and back-end engineers, product, design, and analytics, working closely together to run experiments, ship iteratively, and collaborate with other iwoca teams to share data and infrastructure.

The role

As a Back End Engineer in the Credit Compass New Data squad, you’ll help integrate richer data sources (Open Banking, credit reports) into our product. The aim is to deliver increasingly insightful information to small business owners to help them understand their credit position, and decide what to do next.

Impact on customers

• Assist in building, testing, and shipping new user-facing features on our roadmap (such as Monitoring, Cashflow Analysis and Spend Benchmarking).
• Help ensure the accurate transformation of raw Open Banking, credit bureau, and internal data into clear visualisations and nudges that empower customers to take confident next steps.

Ownership and delivery

• Contribute to the full development lifecycle—from supporting technical design and implementation through to rollout—for well-defined components and tasks.
• Learn to maintain and support the core systems behind Credit Compass, focusing on code quality and reliability.
• Assist in monitoring and troubleshooting production issues, helping to protect user trust and product performance.

Collaboration

• Partner with Product, Design, and Data to understand customer needs and contribute to solutions that balance technical feasibility with user impact.
• Actively participate in squad rituals—from planning to retros—by sharing context, asking clarifying questions, and helping the team achieve its goals.
• Write clean, well-tested code in Python/Django, and actively engage in code reviews to learn best practices and maintain quality across the codebase.
• Help improve internal tools and CRM integrations that speed up our response to user behaviour and reduce manual work.

The requirements

Essential

• Experience building and maintaining back-end services in Python, ideally with Django, including designing and consuming API endpoints.
• A basic understanding of relational databases (ideally PostgreSQL) and an eagerness to learn how to query and integrate third-party APIs.
• Strong verbal and written communication skills, with the ability to translate technical work into clear updates for the team.
• A curiosity and product mindset: you are eager to understand how your work impacts customers, and you are open to using experiments and metrics to guide your decisions.
• Experience writing automated tests, and a high level of attention to details to ensure safe releases.

Bonus

• Experience with relational databases (ideally PostgreSQL).
• Familiarity with integrating complex external services (e.g. Open Banking, credit bureaus).
• Experience leading projects end-to-end, from designing to executing a solution.
• A strong numerical or technical background, with a degree in maths, physics, computer science, engineering, or relevant industry experience.

The salary

We expect to pay from £60,000 - £75,000 for this role. But, we\'re open-minded, so definitely include your salary goals with your application. We routinely benchmark salaries against market rates, and run quarterly performance and salary reviews.

The culture

At iwoca, we prioritise a culture of learning, growth, and support, and invest in the professional development of our team members. We value thought and skill diversity, and encourage you to explore new areas of interest to help us innovate and improve our products and services.

The offices

We put a lot of effort into making iwoca a great place to work:

• Offices in London, Leeds, Berlin, and Frankfurt with plenty of drinks and snacks.
• Events and community-led groups, including running groups, padel, and monthly ping-pong and pool competitions.

The benefits

• Flexible working hours.
• Medical insurance from Vitality, including discounted gym membership.
• A private GP service (separate from Vitality) for you, your partner, and your dependents.
• 25 days’ holiday per year, an extra day off for your birthday, the option to buy or sell an additional five days of annual leave, and unlimited unpaid leave.
• A one-month, fully paid sabbatical after four years.
• Instant access to external counselling and therapy sessions for team members that need emotional or mental health support.
• 3% Pension contributions on total earnings.
• An employee equity incentive scheme.
• Generous parental leave and a nursery tax benefit scheme to help you save money.
• Electric car scheme and cycle to work scheme.
• Two company retreats a year: we’ve been to France, Italy, Spain, and further afield.

And to make sure we all keep learning, we offer:

• A learning and development budget for everyone.
• Company-wide talks with internal and external speakers.
• Access to learning platforms like Treehouse.
